Windows passwords easily guessed by 25-GPU server



Windows passwords easily guessed by 25-GPU server



Ever wondered how secure the password to your Windows workstation is? Well, as it turns out, it's pretty insecure when put up against a 25-GPU server cluster running a combination of Linux and freely available password-cracking software suites. Said server, powered by 25 AMD Radeon graphics cards, manages to brute force Windows passwords at a rate of 350 billion guesses-per-second, making short work of eight-character passwords.

In around 5.5 hours the server cluster can try 6.6 quadrillion password combinations, enough to check every possible eight-character password including upper/lower-case letters, digits and symbols. Microsoft's NTLM cryptographic algorithm, which has been in use since Windows Server 2003, now seems remarkably weak and particularly insecure in some enterprise settings. With access to a hash of a workstation password, this machine will most likely be able to crack it in under a day.

Of course, this machine can only really guess passwords up to eight characters in a reasonable time, as adding just one extra character (to nine characters total) would require 500 hours to crack; 10 characters and you're looking at 5.4 years of cracking time. However, as many businesses stipulate eight characters as a minimum, there's a possibility that this machine will make (relatively-speaking) short work of it.

This 25-GPU machine is not limited to just cracking Windows passwords - it also has the power to guess at 44 other algorithms at a blistering pace. It attacks SHA1 at 63 billion guesses per second and MD5 at 180 billion guesses per second, although struggles against some super-tough encryption such as SHA512crypt (just 364,000 guesses per second).

What should you make of this information? Don't make your passwords anything less than nine characters long, and of course don't use a word or phrase that might appear in a dictionary.

Things Really Smart People Do...



Things Really Smart People Do...



Most people don't really think much about how they learn. Generally you assume learning comes naturally. You listen to someone speak either in conversation or in a lecture and you simply absorb what they are saying, right? Not really. In fact, I find as I get older that real learning takes more work. The more I fill my brain with facts, figures, and experience, the less room I have for new ideas and new thoughts. Plus, now I have all sorts of opinions that may refute the ideas being pushed at me. Like many people I consider myself a lifelong learner, but more and more I have to work hard to stay open minded.

But the need for learning never ends, so your desire to do so should always outweigh your desire to be right. The world is changing and new ideas pop up everyday; incorporating them into your life will keep you engaged and relevant. The following are the methods I use to stay open and impressionable. They'll work for you too. No matter how old you get.

1. Quiet Your Inner Voice

You know the one I am talking about. It's the little voice that offers a running commentary when you are listening to someone. It's the voice that brings up your own opinion about the information being provided. It is too easy to pay more attention to the inner voice than the actual speaker. That voice often keeps you from listening openly for good information and can often make you shut down before you have heard the entire premise. Focus less on what your brain has to say and more on the speaker. You may be surprised at what you hear.

2. Argue With Yourself

If you can't quiet the inner voice, then at least use it to your advantage. Every time you hear yourself contradicting the speaker, stop and take the other point of view. Suggest to your brain all the reasons why the speaker may be correct and you may be wrong. In the best case you may open yourself to the information being provided. Failing that, you will at least strengthen your own argument.

3. Act Like You Are Curious

Some people are naturally curious and others are not. No matter which category you are in you can benefit from behaving like a curious person. Next time you are listening to information, make up and write down three to five relevant questions. If you are in a lecture, Google them after for answers. If you are in a conversation you can ask the other person. Either way you'll likely learn more, and the action of thinking up questions will help encode the concepts in your brain. As long as you're not a cat you should benefit from these actions of curiosity.

4. Find the Kernel of Truth

No concept or theory comes out of thin air. Somewhere in the elaborate concept that sounds like complete malarkey there is some aspect that is based upon fact. Even if you don't buy into the idea, you should at least identify the little bit of truth from whence it came. Play like a detective and build your own extrapolation. You'll enhance your skills of deduction and may even improve the concept beyond the speaker's original idea.

5. Focus on the Message Not the Messenger

Often people shut out learning due to the person delivering the material. Whether it's a boring lecturer, someone physically unappealing, or a member of the opposite political party, the communicator can impact your learning. Even friends can disrupt the learning process since there may be too much history and familiarity to see them as an authority on a topic. Separate the material from the provider. Pretend you don't know the person or their beliefs so you can hear the information objectively. As for the boring person, focus on tip two, three, or four as if it were a game, thereby creating your own entertainment.

Daily Happy Habits



Daily Habits that Create Happiness


Happiness is the only true measure of personal success. Making other people happy is the highest expression of success, but it's almost impossible to make others happy if you're not happy yourself.

With that in mind, here are nine small changes that you can make to your daily routine that, if you're like most people, will immediately increase the amount of happiness in your life:

1. Start each day with expectation.

If there's any big truth about life, it's that it usually lives up to (or down to) your expectations. Therefore, when you rise from bed, make your first thought: "something wonderful is going to happen today." Guess what? You're probably right.

2. Take time to plan and prioritize.

The most common source of stress is the perception that you've got too much work to do. Rather than obsess about it, pick one thing that, if you get it done today, will move you closer to your highest goal and purpose in life. Then do that first.

3. Give a gift to everyone you meet.

I'm not talking about a formal, wrapped-up present. Your gift can be your smile, a word of thanks or encouragement, a gesture of politeness, even a friendly nod. And never pass beggars without leaving them something. Peace of mind is worth the spare change.

4. Deflect partisan conversations.

Arguments about politics and religion never have a "right" answer but they definitely get people all riled up over things they can't control. When such topics surface, bow out by saying something like: "Thinking about that stuff makes my head hurt."

5. Assume people have good intentions.

Since you can't read minds, you don't really know the "why" behind the "what" that people do. Imputing evil motives to other people's weird behaviors adds extra misery to life, while assuming good intentions leaves you open to reconciliation.

6. Eat high quality food slowly.

Sometimes we can't avoid scarfing something quick to keep us up and running. Even so, at least once a day try to eat something really delicious, like a small chunk of fine cheese or an imported chocolate. Focus on it; taste it; savor it.

7. Let go of your results.

The big enemy of happiness is worry, which comes from focusing on events that are outside your control. Once you've taken action, there's usually nothing more you can do. Focus on the job at hand rather than some weird fantasy of what might happen.

8. Turn off "background" TV.

Many households leave their TVs on as "background noise" while they're doing other things. The entire point of broadcast TV is to make you dissatisfied with your life so that you'll buy more stuff. Why subliminally program yourself to be a mindless consumer?

9. End each day with gratitude.

Just before you go to bed, write down at least one wonderful thing that happened. It might be something as small as a making a child laugh or something as huge as a million dollar deal. Whatever it is, be grateful for that day because it will never come again.

Original 'Hacker Manifesto' Text

File: archives/7/p7_0x03_Hacker's Manifesto_by_The Mentor.txt ==Phrack Inc.== Volume One, Issue 7, Phile 3 of 10 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

The following was written shortly after my arrest... \/\The Conscience of a Hacker/\/ by +++The Mentor+++ Written on January 8, 1986 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Another one got caught today, it's all over the papers. "Teenager Arrested in Computer Crime Scandal", "Hacker Arrested after Bank Tampering"... Damn kids. They're all alike. But did you, in your three-piece psychology and 1950's technobrain, ever take a look behind the eyes of the hacker? Did you ever wonder what made him tick, what forces shaped him, what may have molded him? I am a hacker, enter my world... Mine is a world that begins with school... I'm smarter than most of the other kids, this crap they teach us bores me... Damn underachiever. They're all alike. I'm in junior high or high school. I've listened to teachers explain for the fifteenth time how to reduce a fraction. I understand it. "No, Ms. Smith, I didn't show my work. I did it in my head..." Damn kid. Probably copied it. They're all alike. I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to. If it makes a mistake, it's because I screwed it up. Not because it doesn't like me... Or feels threatened by me... Or thinks I'm a smart ass... Or doesn't like teaching and shouldn't be here... Damn kid. All he does is play games. They're all alike. And then it happened... a door opened to a world... rushing through the phone line like heroin through an addict's veins, an electronic pulse is sent out, a refuge from the day-to-day incompetencies is sought... a board is found. "This is it... this is where I belong..." I know everyone here... even if I've never met them, never talked to them, may never hear from them again... I know you all... Damn kid. Tying up the phone line again. They're all alike... You bet your ass we're all alike... we've been spoon-fed baby food at school when we hungered for steak... the bits of meat that you did let slip through were pre-chewed and tasteless. We've been dominated by sadists, or ignored by the apathetic. The few that had something to teach found us will- ing pupils, but those few are like drops of water in the desert. This is our world now... the world of the electron and the switch, the beauty of the baud. We make use of a service already existing without paying for what could be dirt-cheap if it wasn't run by profiteering gluttons, and you call us criminals. We explore... and you call us criminals. We seek after knowledge... and you call us criminals. We exist without skin color, without nationality, without religious bias... and you call us criminals. You build atomic bombs, you wage wars, you murder, cheat, and lie to us and try to make us believe it's for our own good, yet we're the criminals. Yes, I am a criminal. My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive me for. I am a hacker, and this is my manifesto. You may stop this individual, but you can't stop us all... after all, we're all alike. +++The Mentor+++ _______________________________________________________________________________

Intent

Intent is not a thought, or an object, or a wish. Intent is what can make a man succeed when his thoughts tell him that he is defeated. It operates in spite of the warriors indulgence. Intent is what makes him invulnerable. Intent is what sends a shaman through a wall, through space, to infinity.
